Water Oxidation by a Cytochrome P450: Mechanism and Function of the Reaction
P450(cam) (CYP101A1) is a bacterial monooxygenase that is known to catalyze the oxidation of camphor, the first committed step in camphor degradation, with simultaneous reduction of oxygen (O2). We report that P450(cam) catalysis is controlled by oxygen levels: at high O2 concentration, P450(cam) catalyzes the known oxidation reaction, whereas at low O2 concentration the enzyme catalyzes the re...
متن کاملNatural Borneol Recycling from Cinnamomum camphor chvar. Borneol Oil Residue by Fractional Distillation and Recrystallization
Purpose: To establish an efficient method to recycle natural borneol from Cinnamomum camphor chvar. Borneol oil residue. Methods: The fractions and raffinate of the oil residue of Cinnamomum camphor chvar. Borneol were obtained by fractional distillation, and analyzed by gas chromatography with flame ionization detector (GC-FID) and gas chromatographymass spectrometry (GC-MS). Natural borneol w...
متن کاملThe effect of camphor and borneol on rat thymocyte viability and oxidative stress.
Camphor and borneol are wildly distributed in the essential oils of medicinal plants from various parts of the World. Our study has been carried out to evaluate the effect of these two bicyclic monoterpenes on rat thymocytes. Camphor and borneol at concentrations of 0.5 and 5 µg/mL did not induce significant toxicity on the immune system cells, while a significant increase of thymocyte viabilit...
متن کاملChemosystematics of Juniperus: Effects of leaf drying on the essential oil composition of Juniperus pinchotii
A bulk collection of terminal branchlets was made from J. pinchotii and subjected to drying at 42oC (24 hrs), then stored for up to 24 mos. at 22oC (room temperature, RT). The oils were distilled and analyzed from fresh, 0.5, 1, 2, 4, 8, 16, and 24 mos. storage at RT. The oil yields showed a slight decline initially, but remained fairly constant. Camphor, camphene hydrate and citronellal declin...
متن کاملBorneol inhibits TRPA1, a proinflammatory and noxious pain-sensing cation channel.
Borneol, a natural product isolated from several species of Artemisia, Blumea and Kaempferia, has a widespread use in traditional medicine. TRP ion channels are a class of nonselective cation channel proteins involved in a variety of physiological and pathological processes in mammals. TRPA1, a member of TRP family of cation channels, is involved in plethora of processes including noxious-cold,...
